EXPERIMENTAL DYNAMIC CHARACTERIZATION OF TWO INCINERATOR CHIMNEYS NEAR VERONA (ITALY)

The dynamic measurement system installed to study the dynamic behaviour under wind action and dead loads of two chimneys (60m high) of the incinerator in the Disposal Plant of solid urban refuse near the city of Verona (Italy), is described. The results of the experimental campaign are presented: the analysis of the dynamic response of the structure under wind action and the experimental identification of mode frequencies, shapes and damping. The work is completed with comparisons with numerical results obtained from a FE model.
